Title: Redundant constitution of centralized
Inventor: MUKAEMACHI TAKUJI
IPC: H04Q3/545
Filed: 1979-04-27
Abstract: PURPOSE:To prevent down dependent upon a fault by dividing I/O control units and MODEMs into two groups and by confounding them by switching relay contacts and by switching and connecting them to a normal system alternately at a fixed period or by the program control for fault occurrence of one of groups above. CONSTITUTION:For example, when a fault occurs in one of MODEM M00, I/O control unit IOC00, sub-channel unit SCH0, and data channel unit DCH0 of maintenance center MC, central processing unit CC0 or CC1 detects the faulty position to switch the system to the fault redundant constitution system. Switching relay contacts are operated at a fixed period to communicate information with current station LS. Since the data volume transmitted autonomically from current station LS is not large, transfer of charging data, traffic data, and so on is stopped until restoration at a fault time, so that the system can cope with a fixed interrupt time suifficiently if a small-capacity buffer memory is provided in current station LS and center MC.

Title: Alloying treatment of one surface zinc electroplated steel plate
Inventor: SHIYOUJI MASAHIRO
IPC: C25D3/22
Filed: 1980-04-21
Abstract: PURPOSE: To effectively prevent the generation of an oxide or the like on a plating free surface of a steel plate by subjecting the steel plate to heat treatment at a relatively low temp. in an inert gas in order to remove reaction product water of an adhered substance of the steel plate which is a cause of a surface oxidation of said steel plate prior to the alloying treatment.  
     CONSTITUTION: In alloying the one surface zinc electroplated steel plate by a batch system, said steel plate is subjected to the heat treatment at a plate temp. of 100W 200°C for 2hr in an inert gas atmosphere. Subsequently, the aforementioned temp. is raised to attain the alloying. A compound such as Zn(OH) 2 , FeSO 4 .7H 2 O or the like adhered to said seed plate is decomposed and shows dehydration reaction at 200°C or less and it is considered that the formed H 2 O promotes the oxidation of a plate surface. When the aforementioned heat treatment is carried out, because said H 2 O is removed when a plate temp. is low, the oxidation of the plate surface can be effectively prevented.
